I am 3 years experience on Embedded Linux developer, with may driver such as ethernet, wifi, lcd, audio, ... and 1 year experience on OpenWRT firmware development with dir505 wifi router. So I think i can be suitable to your requirements, to develop wifi firmware for your apdapter. I can work hard to complete this work in time.
Ps: I am Duong, from Hanoi, VietNam. If you want to talk about this work, Please add my skype id: hoangduong_lhp.
Thanks,
